To all; whom, t may concern:

. Be it known that I, JOHN 'Cosenovm a citizen of the United States,residing at Medford, in the county of Middlesex and State ofMassachusetts, have invented certain new and .useful Improvements inSole-Molding Presses; and I: do hereby declare thefollowling to be aful1,clear, and yexactdescription Aof Athe invention, suchas will enableothers skilled in the art to which it appertains to make and. 1use thesame.

This invention relates to pressesfor Vmolding soles and 'moreparticularly to such machines forl molding or lbreaking down the marginsof soles for turn shoes. The machine isdesigned for performing thespecific operation of molding the margin about the toe end of aturnsole, the moldingof the remainder of-y the .margin being, performedon another machine.

. Heretofore it has` been the practiceV to break down the marginsof turnsoles by a machine which feeds the margin of the sole progressively pastthe molding tools such, for example, as the Goodyear power moldingmachine disclosed in Letters Patentof theUnited States to William C.Meyer No.

1,110,637, granted'September 15, 1914. It has been found to be diliicultto -feed,.through a machine of this type, the extremely pointed toes onthe-soles now in vogue,l commonly called peakedrtoe soles, withoutydistorting the toe a'ndthus spoiling the lines of the i `shoe whennished;

. In a. co-pending application of Frank E.

Beckman, Serial No. 366,265, filed March 16, n(1920, afnovel pressforeliminating the danger of distortion is described whichl provides.able for width and style.- When an adjustprovide for a substantiallyinstantaneous f ,acter referred to, and thus render the op-A i ment isrequired it necessitates stopping the .operation of themachine for anappreciable period to permit the removal of onemold `Vcouple and thesubstitutionof another.

I An object of the presentinvention isl to adjustmentfor width in apress of the char,-

Qjeration ,of the,l machine .practically ,continuous whenoperatinguponcase lots ofsoles.

Muchtime'is thus lsaved andthe output of.

y.thel machine materially increased.

Accordinglyan important characteristic y I ofthe invention-iis found inlthey construction of. themold couple for breakingdowngthe mar-ginl about,thezgtoe AThismold couple comprises aiamale and female-mold generallybftheBeckman type, each .of which,

however, is madeintwoparts or halves mounted for; articulated" movementabout a center at the tip ofthe toe. Thet-womolds are sointerc'onnectedthat an adjustment,

i; e., an opening or closing aboutthe'tip. of .p the. toe as a center,of one compels lan equal adjustmentv of the otherz- When itlis'considered that thev toe ends of peaked toe soles :are: substantiallytriangular in plan, it. willk be :understood that the adjustment vde-i:scribed-will accurately provide for a -large i number of. widths`without necessitating a` removal Vof the mold couplefrom the machine'.y

such others as may hereinafter appear, asV willvbe' readily understoodby those skilled yinthefart,the invention comprisesy the features andcombination ofparts hereinafter describedand then particularly pointedout inthev appended claims. l y f a Y *The features of the inventionwill be best understood from a description of thepreferred' Aembodimentthereof illustrated' in the accompanying drawings, in which:

- .y l-Tothe accomplishment of this object and Figure l is ay frontelevation of the workingpartsof the machine; Fig. 2 is a` front`elevation of the mold couple with the toe end a In the lembodiment yofthe invention illusa trated in the drawings the y. sole molds .have beenapplied to a pressrvof the typed-isclosed in Letters Patent of theUnited States lto Lorenzo P. Hawkins, No. 514,364, granted February 6,1894.v As in the machine of said Hawkins patent a table 10, supportedlat a block 12 having oppositelyy disposed vears 14.

The lower o'r'male mold block 16 is removtably secured to thebase blockby screwslj fthreadedf'into definitely located receivingl 'boresinthefears 14.v`r

A ove'the ymoldblock ing 18fcarijied at the forward 'end of theyfconvenient'- height, is provided with a basey l1e. is eternal tear-` fto theupper end of which is suitably jointed Y the rod 24 of aneccentric strap 26 embracingan eccentric 28 on the forward end of a'power Yshaft'BO driven by a pulley 32. rllw'o journals for the shaft 80rise from the frame 20 of which the forward one 34 only is shown. Therevolution of .the shaftBOyis controlled by -a 'clutch (not shown),operated by' a treadle attached to the treadle rod 36, designed toprovide for a sustained pressure onthe sole placed -between the molds asis common to presses of this general type.

The upper or female mold is secured to 'a sustaining block 38 which isprovided with a centering pin 40 vfittir'ig within a bore in the plunger22 and is thus definitely positioned with relation to the lower or malemold block 16. The block 38 is secured to the plunger in any convenientmanner as by a set screw 42.

YThe mold supporting blocks 16 and 38 are provided respectively witharcuate dovetail ways 44 and 46 the centers of which are at the tip ofthe toe of the mold couple. These ways form tracks for guiding themovement of the separately formed halves of therupper and lower moldsduring adjustment thereof.

The lower or male mold is formed in two halves 48 and 50, onecomplemental to the other, and together forming a sole supportingsurface generally triangular in plan, the upperside edges of whicharebeve'led vas at 52 to form oblique sole margin engaging walls. c

The male mold halves 48 and 50 rise from base portions 54 and 56 whichare provided o n their under faces with dovetail ribs 58 and 60 shapedto fit and slide inthe lower way 44. Outside the male mold halves 48 cof the sole.

and 50, and integral with thebase portions, are two outer members 62 and64 the inner surfaces of which are' parallel to the outer surfaces ofthe male mold halves but spaced therefrom to form vertical slots 66 and68. The movable parts thusy far described are connected by a hinge 70,of usual form, the pintle 72 of which has its axis at the tip lof thetoe end of the mold as shown in Figs. 3 and 4. Y

The upper or female mold is also formed in two separate halves 74 and76, one complemental to the other and having depending legs 7 8 and 8Orespectively which are so shaped as to slidingly fit the two slots 66and 68. Each female mold, within its depend- `ing leg, is provided withoblique side walls 82 to engage the margin of the solejand vertical sidewalls 84 4to engage Vthe shoulder The female mold halves are providedwith dovetail ribs 86 and 88 shaped to fit and slide in the upper way46. A

cylindrical pin 90 is secured in the lower face of the .upper mold:block' 38 with its'fcenter above the axis of the lhinge pintlef-72, thefemalemold halves being cutaway at their rear corner to partiallyembrace it (see Fig. 3).V It will be observed that. the con- Y structionjust described provides lfor asimul- -taneous. Vmovement of both themale and female mold halves at either side of the mold couple wheneither the upper or lower mold is adjusted. Y

in order to effect an adjustment 'of the mold couple to provide formolding Asoles of different widths, an adjusting plate is providedhaving a connection with both of the male mold baseportions 54 l'and 56.c

These portions are provided with an oblique slot 92 and 94 (Fig. 3)'into which take rolls 96 and 98 carried by a sliding plate 4100 seatedin a way-102 formed in the mold block 16. rlhe plate V100 has a downturned ear 104 slotted to receivek the stem of an adjusting screw 106threaded into t-he block 16. Collars on the lscrew insure a movement ofthe plate 100 and consequently of the rolls within the slots, in onedirection or the other, when the screw is turned. It will be obviousthat if the plate 100 is moved outward the mold halves, both male andfemale, areV moved apart, and'if moved inward'they will be vdrawntogether, angularly about the hinge Y7() and pin 90 as an axis.

The throw of the eccentric 28 is notso great as everto withdraw the legs78 and 80 the operator thrusts ing in contact with the outer surface ofthe male mold forming an accurate gage for the edge of the sole tocorrectly center it between the members of the mold couple.v

The clutch is then thrown in andthe female mold descends4 gripping themargin'of rthe sole between the oppositely disposed oblique side wallsand forcing they shoulder within the recess formed by the moldwalls 84as shown in Fig. 2. Adjustment for "width is quickly effected by thescrew 106, ascale,V as usual, being provided for accuracy.

Those skilled in the art will recognizeV that some featuresV of theinvention,r are not limited to akmold couple having theadjustnient forwidthl which formsthe principal feature, but'may be 'employed in anymold couplefor breakingdown themargin `at the toe end ofthe 'turns'olesvThe nature and scopefof the present-` invention havingbeen indicated'andthe preY`lferred embodiment of the invention having been specificallydescribed, what is claimed as new, is
